Abstract
An ultrasonic imaging system is described in which a column-row-parallel architecture is provided at the circuit level of an ultrasonic transceiver. The ultrasonic imaging system can include a N×M array of transducer elements and a plurality of transceiver circuits where each transceiver circuit is connected to a corresponding one transducer element of the N×M array of transducer elements. A shared pulser gate driver and a shared VGA is provided for each row and column. Selection logic includes row select, column select, and per-element bit select. Through the column-row-parallel architecture, a variety of aperture configurations can be achieved.
